Police stand near a truck that ploughed into a crowd leaving a fireworks display in the French Riviera town of Nice on July 14, 2016

Paris (AFP) - Thursday's attack on the Champs Elysees in Paris saw a gunman kill a policeman and wound two others in bloodshed claimed by the Islamic State group just days before an election.

Observers had long feared bloodshed ahead of Sunday's vote and the violence is likely to thrust security to the front of voters' minds.

Here is a recap of major attacks and foiled attempts since the Charlie Hebdo shootings in Paris in January 2015.

- January 7-9: Two men armed with Kalashnikov rifles storm the Paris offices of satirical weekly Charlie Hebdo killing 12 people. A policewoman is killed just outside Paris the following day, while a gunman takes hostages at a Jewish supermarket, four of whom are killed. The attackers are killed in separate shootouts with police, but not before claiming allegiance to Al-Qaeda and the Islamic State (IS).

- February 3: A knife-wielding man attacks three soldiers guarding a Jewish community centre in Nice on the French Riviera. The 30-year-old assailant, Moussa Coulibaly, is arrested. In custody, he expresses his hatred for France, the police, the military and Jews.

- April 19: Sid Ahmed Ghlam, an Algerian IT student, is arrested on suspicion of killing a woman who was found shot dead in her car, and of planning an attack on a church in the Paris suburb of Villejuif. Prosecutors say they found documents about Al-Qaeda and IS at his home, and that he had been in touch with a suspected jihadist in Syria about an attack on a church.

- June 26: Frenchman Yassin Salhi, 35, kills and beheads his boss Herve Cornara and displays the severed head, surrounded by two Islamic flags, on the fence of a gas plant in Saint-Quentin-Fallavier in southeastern France.

- August 21: Passengers prevent a bloodbath on a high-speed Thalys train from Amsterdam to Paris, tackling a man who opened fire on travellers. He was armed with a Kalashnikov assault rifle, an automatic pistol and a box-cutter. The gunman is identified as 25-year-old Moroccan national Ayoub El Khazzani, known to intelligence services for links to radical Islam.

- November 13: IS jihadists armed with assault rifles and explosives strike outside a France-Germany football match at the national stadium, Paris cafes, and the Bataclan concert hall in a coordinated assault that leaves 130 people dead and more than 350 wounded, the deadliest attack of its kind in French history.

- 2016 -
